Reiroukan is a beautiful house that is currently renting rooms to male and female students. Shirai Genta has just moved to Reiroukan, turning over a new leaf in his life. The house is full of other people with strong personalities, such as the nerdy Tokimaru and the careless and uninhibited Mikoto, who frustrates her friend Midori with her messiness. Genta gets embroiled in all sorts of wacky situations. Soon, though, Genta finds that Reiroukan is scheduled to be closed in a year. At least, there is still a year for Genta to build fond memories with the lively inhabitants of the house!

Reiroukan Kenzai Nariya follows the plot of a bunch of eccentric people each with their unique personalities living in a dormitory situated in an old building scheduled for demolition. What seems incoherent in the first few chapters starts making more sense in volume 2.

The sheer number of residents makes it difficult to have a background story for each. Character development consequently is limited. The ecchi is unnecessary and the story would have been fine without it. One good point is that the mangaka provides a satisfactory ending to the series.
